ReactiveSwift 简单使用

记录 ReactiveSwift 简单使用

1. 导入 ReactiveSwift 库
2. 创建 TestViewModel 文件

enum JKTypeType: Int {
    case cloud
    case device
    case weater
}

// 通过监听属性变化
class TestViewModel: NSObject {
    
    lazy var recordType: Property<JKTypeType> = {
        return Property(recordTypeProperty)
    }()
    
    private(set) var recordTypeProperty: MutableProperty<JKTypeType> = MutableProperty(.device)

    deinit {
        print("TestViewModel delloc")
    }
}

extension TestViewModel {
    
    func setRecordType(_ type: JKTypeType) {
        recordTypeProperty.value = type
    }
    
}

3. 使用 TestViewModel

class RegisterVC: UIViewController {
var testViewModel =  TestViewModel()
    
    let disposes: CompositeDisposable = CompositeDisposable()

override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = UIColor.white
        bindViewModel()
    }

func bindViewModel() {
         disposes += testViewModel.recordType.signal.observeValues { type in
            print("testViewModel: \(type)")
        }
    }


@IBAction func backClick(_ sender: Any) {
        testViewModel.setRecordType(.cloud)
     }
}

deinit {
        disposes.dispose()
    }
